Rev 1.1 Schematic — H-ig41-uatx

The board is frequently used in business and budget-focused HP/Compaq models, such as the Compaq CQ3212L and HP Compaq 500B. Known Issues & Troubleshooting

If you are working with an H-IG41-uATX Rev 1.1 that has failed, the schematic can help troubleshoot several common issues: 4.1 No Power / No Fan Spin

Use terms like "H-IG41-uATX REV 1.1 schematic pdf" or "Pegatron Eaton schematic" .

A motherboard schematic is the blueprint that outlines the electrical connections, components, and signal paths between the CPU, memory, chipset, and connectors.

Ensure your board says REV 1.1 near the printed model number. Minor layout modifications, trace routes, and component values often change between REV 1.0 and 1.1. h-ig41-uatx rev 1.1 schematic

The H-IG41-uATX is a Micro-ATX motherboard designed for HP, utilizing the Intel G41 Express chipset. It is known as the "Eton" motherboard in HP documentation.

The first pages detail how 12V from the ATX power supply is converted to the required voltages:

The is a legacy motherboard commonly found in budget desktop PCs, OEM systems (such as HP and Compaq machines), and custom low-cost builds from the late 2000s and early 2010s . Built around the Intel G41 Express chipset, this motherboard bridges the gap between older DDR2 memory systems and early DDR3 platforms, making it a frequent subject for repair technicians, hobbyists, and retro-computing enthusiasts. The board is frequently used in business and

The , often known as the HP Eton or Foxconn H-IG41-uATX , is a legacy motherboard commonly found in HP Compaq desktop systems from the late 2000s and early 2010s. Based on the Intel G41 Express chipset and supporting the Socket LGA775 architecture, this microATX board was designed for reliability in corporate and home office environments.

: Located near the bottom-right edge. It manages the power button, reset button, and status LEDs. Pin 1 is typically marked with a small triangle.

These provide power to the core silicon of the G41 GMCH and ICH7 chips respectively. Short circuits on these rails usually indicate an internally damaged chip, common after a major power surge via USB or Ethernet. Common Failure Points and Troubleshooting via Schematic
